Abstract

The present invention discloses a Keyboard-Video-Mouse (KVM) cable capable of indicating at least one switching status of a KVM switch for at least one computer coupled thereto. The KVM cable further comprises a set of transmission lines for transmitting indicating signals from the KVM switch to the indicator. The KVM cable comprises a plurality of connectors. A first indicator may be disposed on a first connector for indicating a console switching status. A second indicator may be disposed on a second connector for indicating a peripheral switching status. Alternatively, both the first and second indicators can be disposed on the same connector for indicating the console switching status and the peripheral switching status respectively. Moreover, a color mixing LED may also be disposed on either of the first and second connectors for indicating the console switching status and the peripheral switching status by different colors.
